At the turn of the 20th century, bicycling enthusiast and Pittsburgh native, Frank Lenz was an American celebrity. His two wheeled global journey, and eventual disappearance in Turkey, are chronicled in David V. Herlihy's book The Lost Cyclist. Last year Herlihy came to Pittsburgh and Essential Pittsburgh to celebrate Frank Lenz Day. This year, in observation of Lenz's world tour departure, we look at Pittsburgh's place in cycling history with WESA reporter Margaret Krauss.
